A student observes what happens when he releases a wadded-up piece of paper, a baseball, and a rock from one meter above the ground all at the same time. All three objects move in the same direction. Part A Which claim can be made based on the student’s observations?

• The volume of the objects causes the objects to fall down toward Earth.

• The rotation of Earth causes the objects to fall down toward Earth.

• The density of the objects causes the objects to fall down toward Earth.

• The gravitational force of Earth causes the objects to fall down toward Earth.
